I'm not sure that the problem is on the line where the error is
reported. My guess would be that the issue is with the "auto a = new
Bar" line: I would bet that this gets interpreted as "Foo a = new
Bar" instead of what we expect ("Bar a = new Bar"). If I'm right,
then the "a = null" line is indeed an error: since Foo is a struct
and structs are value types, you cannot affect "null" to a variable
of type Foo...
No, that's not the case. Here is an updated test case, without any auto's:
-----
struct Foo {}
class Bar {
Foo foo_;
alias foo_ this;
}
void main() {
Bar a;
a = null;
}
------
aliasthis1.d(8): Error: cannot implicitly convert expression (null) of
type void* to Foo
So it seems to be a real problem. I've reported it in Bugzilla:
